Setting the Low Pass Filter (LPF)

The Auro D1200 LPF (low pass filter) control gives you the ability to tune the
subwoofer to match your sound and room. The LPF control adjusts the internal
crossover of the subwoofer from 80Hz-200Hz. Use the below points as guidelines
when setting up your sound system, but always use and trust your ears when finding
a setting that sounds good and fits your application.
The goal is to seamlessly integrate the subwoofer with rest of your speakers to extend
the frequency range of your system, rather than produce an unnatural, boomy mix.
You do not want the subwoofer and the main speaker to reproduce the same frequen-
cies, as this will create duplication of low frequencies, and create an imbalanced
mix.
A good place to start is to use the frequency response of your speaker cabinets. You
can usually find this information in the documentation included with your speak-
ers. Set the Auro D1200 subwoofer LPF to the lowest frequency that your satellite
speaker produces.
If your satellite speakers are large (12" or 15") set the low pass filter to 80Hz. If
your speakers are small (8" or 10") set the low pass filter in the 100Hz range. If you
have an oscillator (there are many free oscillator smartphone and tablet apps avail-
able), slowly sweep from 400Hz down to 40Hz, and listen to how the subwoofer and
speakers blend together. You may need to raise or lower the LPF control to create the
smoothest frequency response.
If you do not have an oscillator, use music tracks that have a steady bass line and
kick drum. Slowly adjust the LPF until you find the optimum setting.
